Bought like 2 months ago a new CPU E8400 since my wife's computer toasted and gave her my old E6750.

Still on stock cooler .. ordered the Thermalright LGA775 RM kit for my old XP-90C siting in a box.

I managed to get a prime stable at 4ghz at 1.250v in bios. Far from being an expert on that chip but i think its decent. Havent tried over 4ghz yet since i'm on the stock cooler. 33C idle / 61C full load. And wondering if my old XP-90C will still be good on this chip.

great OC with low vCore.....
Did you run P95 Blend for around 8 hrs...what were your Load Temps? That was on a Stock Cooler or am I misreading your Post?
I would imagine a full P95 stability test on a a Stock HSF at 4 Ghz would have very high Temps..

Yeah Blend over 8 hrs on stock cooler (while sleeping) around 61C (was that temp when i checked the morning) but recorded as 63C max temp during the night.

my LGA775 RM kit is out for delivery today .. the UPS guy should be there soon so i'll install my old XP-90C! Cant wait hopefully the temp will improve a lot .. i hope for like 10C dunno if i'm asking too much

Out of curiosity is Arctic Silver 5 still pretty good or i should use my old thermal paste that came with my XP-90C ?

Yeah i got like 9C cooler with the XP-90C but that's with the case open .. with my case closed i'm up at like 58C full load in crossfire (XP-90C at 4ghz). but my air flow in this case is terrible .. Antec Sonata II there's just like a 120mm fan at the back sucking the air out of the case and a kind of annoying air chamber providing "fresh air" directly to the cpu. I could still fit that "exhaust" removing a piece of it.

I stay below 65C (Full load) on my CPU, the E8400 I have is similar in OC ability to yours, so I've benchmarked it with as high as 1.5vcore. 24/7 use, I'm more into longevity and am happy with this 4GHz @ 1.25
